One or more information maps are obtained by an agricultural work machine. The one or more information maps map one or more agricultural characteristic values at different geographic locations of a field. An in-situ sensor on the agricultural work machine senses an agricultural characteristic as the agricultural work machine moves through the field. A predictive map generator generates a predictive map that predicts a predictive agricultural characteristic at different locations in the field based on a relationship between the values in the one or more information maps and the agricultural characteristic sensed by the in-situ sensor. The predictive map can be output and used in automated machine control.

A blast pressure recording device and method includes at least one first sensor for measuring a parameter indicative of a blast event, at least one comparator in communication with the at least one first sensor for determining whether said parameter indicative of a blast event exceeds a predetermined threshold, at least one second sensor for measuring blast pressure, a power control means providing power to the at least one second sensor only when the predetermined threshold is exceeded, and a controller for receiving and recording blast pressure.

A surge control system and method include a valve assembly located along a fluid conduit downstream of one or more compressors in a flow circuit, and configured to receive a fluid stream from the one or more compressors. The valve assembly includes a valve body, a pitot tube integrated onto the valve body, and a pressure sensor device operably connected to the pitot tube. A controller of the surge control system receives pressure measurements generated by the pressure sensor device. The pressure measurements represent pressure in the pitot tube over time. The controller analyzes at least one of (i) the pressure measurements or (ii) flow velocity values derived from the pressure measurements, and detects a surge condition in the flow circuit based on oscillations in the at least one of the pressure measurements or the flow velocity values.
